Between the upper frame bar .13 andanintermediate cross bar 16 the easel carriesa ground plate17 to which are 86 asted or otherwise secured in their successive 'order'plates 18, 19, and20, (Figs. 8, 9 and 10), each containing a median oval or elliptical opening 21, a square opening 22 at one side hereof, and asubstantially S-Shapedopen- 85 ing' 23' at the otherside of said median-opening'. A front plate 24 has a median opening 25 and square opening 26 and a substantially 8-.shaped opening 27 at the sides of opening 25, and is pasted on plate 20, so that pockets are formed by the overlapping plates.

The ope'nings are surrounded by allegoric figures of animals in squares 28, and lateral,

upper and lower panels 29,30, 31.

.In the median ovalopening 25, filler members 32, 33, 34 'and 35 are pasted to plate 20 by means of their rear cleats- 36 which leave the margins 37 on the member's projecting beyond the cleats to form inner guideways for the buttons 38.

drawings that the turn or curve from the parallel straight lines channel between members 33 and 34 to the outer or oval channel is such as to meet the outer oval channel at almost a right angle in order to allow a movement of the blocks in a narrow channel so that when sitting in an upright or almost upright position, as part of the easel blackboard, the blocks will pass in or out of the curve without locking. And this I consider the most vital part of my invention. 1 i. I The outer edges of each two adjoining members are separated to leave passageways 38, 39, and 40 respectively and the outer lower ends of the edges of member 32and inner upper edges of member 33 and the lower end edges of member 34 have rounded shoulders 42, formed therewith.

I

The openings 26 and 27 in thesuperposed plates form pockets for the reception of a plurality of pieces of var'i-colored chalk in opening 26 which is closed by fiap of flexible ma- .terial glued or otherwise secured along its upper edgeto the wall in front plate 24 formthe lower, free edge of. said flap adapted to be engaged into a pocket formed from blank 46 by bending the edges thereof along the dotted lines shown in Figure 5 and placed in the lower part of opening 26 by gluing or otherwise securing the bent edges to the walls forming said opening, said flap having a handle 47 attached thereto.

An eraser or wiper having a back 48 and a wiper'material 49 attached thereto is adapted to be placed into pocket 27.

A plate 50 is set in the rear frame 11 and carries a book or paper shelf composed of a plurality of substantially vertical bars 51 and longitudinally extending cross" plates 52 allowing a convenient insertion of sheets or drawing cards 53 orthe like into the shelf.

A plate or table 54 in a frame 55 is on its upper face velvet finished to form a desk plate while its other side forms theslate. In its 7 position as desk plate the side edges of the plate 54 rest on brackets 56 having an upper shoulder 57 engaging a pin 58 projecting from the front face of the legs to frame 10.

The brackets 56 serve also as'supports for the lower'edge of the table when the plate 54 is turned to present the slate to the front,

' It is to be understood that I have disclosed the preferred form of my device-as one example of the many possible ways to practically construct the same. andthat I may make such changes in the general arrangement thereof and in the construction of its minor details as come within the scope of the appended claims without departurefrom my invention and the principlesinvolved. V Having thus described my invention,.what- I claim as new and desire to secure by Letters Patent is: l

1. In aneasel blackboard of the class described, members forming guide channels for buttons between themselves and an outer channeled member, the outer ends of the I circular channel at nearly a right angle and Wlll allow inner of said members turned or curved, the I turn or curve leading from the guide chan nels between said inner and the outer members meeting the outer oval channelat ap-' proximately a right angle allowing the buttons to passinor out of the curve without arnan an blackbcard of the ass at;

scribed, a plate having a median oval opening, a base for said plate, the edges of said plate projecting beyond said base and surrounding said opening, filler members, rear cleats on said members allowing a pasting of said filler members to said plate within said opening, two of said members constituting outer members having curved outer edges and straight inn-er edges, and two other of said members constituting inner or central members having straight side edges forming with the straight inner edges of said outer members and with their inner parallel side edges channels, rounded shoulders formed with the inner upper end edges of the central members and the lower end edges of said outer members to form outlets for said channels for allowing the passage of blocks in and out of the channels avoiding locking and allowing a smooth and rapid movement of said blocks in and out of said channels.

3. In an easel blackboard as described, a member provided with an oval opening, a base therefor, said member having the edge forming said oval opening projecting beyond its base, and a plurality of intermediate members, bases for said members, the edges of said members projecting beyond their bases to form straight channels with each other and a curved channel between the outer of said members and said member having the oval opening for the guidance of buttons, the outer ends of the inner of said members turned or curved, the turn or curve from the straight channels between the inner of said members meeting the outer curved channel at a right angle allowing the buttons to pass in or out of the curve without locking.
